| Spacetime Geometry and General Relativity - Neil Lambert The plan of the course is as follows. We will first review Special Relativity. It is assumed that you have a reasonable knowledge of this as well as tensors such as those encountered in Electromagnetism. We will review (or perhaps introduce) covariant index notation and spacetime. Next we will discuss Einstein's famous thought experiment and follow his logic that leads to the notion that, in the presence of gravity, spacetime is curved...

Cook Maxwell's equations of electromagnetism describe three dimensional electric and magnetic field line divergence and curl (rank 1 tensors, or vector calculus), but were compressed by Einstein by including those rank-1 equations as components of rank 2 tensors. However, Einstein did not express the electromagnetic force in terms of a rank-2 spacetime curvature. In order to unify or even compare the equations for two forces (gravity and electromagnetism), you need first to have them expressed in ter...

In this way, resulting solutions are found �rst and the initial conditions are obtained subsequently. In this chapter it is appropriate to return to the original problem of specifying the initial data and then attempting ...

| Colliding Plane Waves in General Relativity- Chapter 20 - Other Sources - Jerry Griffiths So far only solutions of the Einstein or Einstein-Maxwell equations have been considered. This has enabled the properties of colliding plane waves to be considered in the various cases in which the approaching waves were gravitational waves, pure electromagnetic waves, or combinations of both. A number of similar results have also been obtained for a variety of other sources. These will be reviewed in this chapter.

In this case the �eld is described in terms of a complex potential function that is referred to as the Ernst potential (see Ernst 1968a). This approach leads directly to various methods for generating further exact solutions.

Following this pioneering work, many more exact solutions have been obtained.
